The potential mechanisms linking early experience and temperament to coping with common peer dynamics and the stress hormone cortisol were explored for young women in two studies. Girls and women typically use friendships, ...
High school principal communication and organizational knwoledge [sic] creation
(University of Missouri--Columbia, 2007)
The purpose of this study was to determine what impact, if any, does effective communication by high school principals have on the knowledge creation capacity of the school. A mixed research design was utilized. Quantitative ...
Comparing perceptions about collaborative culture from certified and non-certified staff members through the adaptation of the School Culture Survey - Teacher Form
(University of Missouri--Columbia, 2007)
The purpose of this quantitative case study was twofold. The first purpose of this study was to create a parallel instrument to the School Culture Survey-Teacher Form in order to gauge the cultural perceptions of non-certified ...
Adjustable speed drive bearing fault detection via support vector machine incorporating feature selection using genetic algorithm
(University of Missouri--Columbia, 2007)
This dissertation presents a novel method to detect bearing defects in Adjustable Speed Drives (ASD's), which are increasingly used in many commercial and industrial applications. The harmonics in pulse-width-modulation ...
Regulations and functions of P2Y₂ and P2X₇ nucleotide receptors in the central nervous system
(University of Missouri--Columbia, 2007)
It is well known that ATP acts as a classic neurotransmitter in the central nervous system. It is stored in synaptic vesicles, released upon neuronal excitation, and activates both ion channel receptors (P2X) and G ...
An ecological systems approach to reduce children's encounters with obscenity on the internet
(University of Missouri--Columbia, 2007)
This dissertation explores how to reduce children's encounters with obscenity on the Internet. Congress has been trying to shield children from encountering online obscenity and some of Congress' attempts failed because ...
Identification and characterization of M cells in the mammalian conjunctiva
(University of Missouri--Columbia, 2007)
The M cell is a morphologically and functionally distinct epithelial cell found in the follicle associated epithelium (FAE) above organized lymphoid tissue at distinct locations along mucosal surfaces. By sampling antigens ...
Flexure shear response in fatigue of fiber reinforced concrete beams with FRP tensile reinforcement
(University of Missouri--Columbia, 2007)
The primary goal of this MODOT-sponsored investigation is to characterize the flexural shear response, fatigue behavior, and performance of fiber reinforced concrete flexural sections with fiber reinforced polymer tensile ...
Oil price shocks and stock market behavior : empirical evidence for the U.S. and European Countries
(University of Missouri--Columbia, 2007)
This dissertation analyze the relationship between oil price shocks and stock market for the US and 13 European countries with monthly data from 1986.1-2005.12. Three countries (Denmark, Norway and the UK) among 13 European ...
Optical stimulation of quantal exocytosis on transparent microchips
(University of Missouri--Columbia, 2007)
Photorelease of caged Ca²⁺ is a uniquely powerful tool to study the dynamics of Ca²⁺-triggered exocytosis from individual cells. Using photolithography and other microfabrication techniques, we have developed transparent ...
Maintaining cross-domain objects and features in working memory : implications for storage in models of working memory
(University of Missouri--Columbia, 2007)
A great deal of evidence, both from behavioral studies of cross-domain interference and from neuroimaging, suggests the need for a domain-general store in models of working memory. Baddeley included such a store in an ...
Exploring the relation between cigarette smoking and alcohol hangover frequency
(University of Missouri--Columbia, 2007)
Drinkers differ meaningfully in their susceptibility to hangover, and prior studies suggest individual differences in hangover proneness may be related to risk for alcohol use disorders (AUD). This project examined whether ...
Clinical content tracking system: an efficient request tracking via a graphical user interface
(University of Missouri--Columbia, 2007)
We propose a new system called Clinical Content Tracking System (CCTS) that is a pre-component of a Computerized Physician Order Entry (CPOE) system. CCTS is a tool that helps physicians build clinical contents, in an ...
The other within: prismatic identities and authentic selves within the marginalized
(University of Missouri--Columbia, 2007)
This article's aims are three-fold: First, it attempts to problematize the current essentialist positions of identity formation, particularly that of the Other, within the social sciences. It attempts to explore how the ...
Laramide stress conditions and deformation mechanisms during the formation of Derby and Dallas Domes, Weiser Pass Quadrangle, Wind River Mountains, Wyoming
(University of Missouri--Columbia, 2007)
Uplift of the Wind River Mountains during the Laramide orogeny (ca. 80-40 Ma) produced a NNW-SSE series of southwest-verging, asymmetric, doubly plunging folds along the northeastern margin of the range. This fold series, ...
Evaluating the suitability of the human toenail as a biomonitor for manganese status: the one source cohort
(University of Missouri--Columbia, 2007)
Numerous studies have demonstrated that the human toenail is a reliable biomonitor for the intake of Se and other elements. The objective of this study was to evaluate the hypothesis that Mn intake is reflected in toenail ...
In vitro three dimensional biomechanical comparison of two internal fixation methods in equine adult radii
(University of Missouri--Columbia, 2007)
Radius fracture configurations conducive to internal fixation most often contain a spiral or oblique fracture of the distal diaphysis. The location and fracture configurations are biomechanically challenging because of the ...
Variation in the flood tolerance of three midwestern oak species
(University of Missouri--Columbia, 2007)
Several studies on flood tolerance of hardwood seedlings have suggested ecotypes exist among seed sources related to past flooding history and soil hydrological properties of the collection site. Our study examined differences ...
Reaching union families: collective identity, union advantages and the American ethos
(University of Missouri--Columbia, 2007)
The present study examines the beliefs of union family members. Through analysis of qualitative interviews with union members and their wives and adult children, I investigate three main themes: 1) the benefits of unions, ...
